Python 如何在SqlAlchemy/Postgres中查询数组,python,mysql,arrays,postgresql,flask-sqlalchemy,Python,Mysql,Arrays,Postgresql,Flask Sqlalchemy,我有一张像这样的桌子 class Company(db.Model): __tablename__ = 'company' company_id = db.Column(db.Integer, primary_key=True) name = db.Column(db.String) slug = db.Column(db.String) tags = db.Column(ARRAY(db.Integer), index=True) invest

我有一张像这样的桌子

class Company(db.Model):
    __tablename__ = 'company'
    company_id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String)
    slug = db.Column(db.String)
    tags = db.Column(ARRAY(db.Integer), index=True)

    investments = relationship("Investment", back_populates="company")

我想编写一个查询，返回数组（标记列）中具有某个整数（比如6）的所有行，我尝试了以下方法

（1）给我以下的错误

ProgrammingError: (ProgrammingError) missing FROM-clause entry for table "company"
LINE 3: WHERE 6 = ANY (company.tags)

（2）给了我意想不到的行为。它要么不返回任何信息，要么返回所有信息。过滤器坏了。 ^

ProgrammingError: (ProgrammingError) missing FROM-clause entry for table "company"
LINE 3: WHERE 6 = ANY (company.tags)
